Hydraulic motors

The realization of customer-specific solutions is one of our core competences. We offer a comprehensive / diversely differentiated range of hydraulic motors and, in particular through the combination of downstream brakes and gearboxes, a multitude of sophisticated drive solutions can be realized. Thereby our hydraulic motors convince with their mature construction and assert themselves for decades in rough and demanding application areas.  

Düsterloh has been successfully developing and building hydraulic motors for industrial use for many decades. Our decades of experience in the field of hydraulic drives helps us in the continuous further development of our hydraulic motors.

Gearbox + brake

RM 1250XHA1-SL 18003FS hydraulic brake gear motor

Our hydraulic motors can be combined with any of our one- to four-stage coaxial and right-angle gear units. In addition, spring-applied multi-disc brakes, which are required when holding static loads, can be installed between the motor and the gearbox.

Valve assemblie

RMHP 90 with servo valve encoder

The valve assemblies are available for different connection patterns and with or without shock protection. They are suitable for all our motors in the A1 version.

Flow distributor

RM 63 power divider

The hydraulic radial piston flow dividers divide the incoming volume flow into several equally sized volume flows at the output. This allows rotatory and translatory drives to be moved as synchronously as possible.


Ball valve KHMFF-80

For the hydraulic area, we offer a wide range of accessories, such as oil expansion tanks, torque supports, shrink discs, rotary encoders, etc.

Hydraulic motor application

The motors were originally developed for harsh use in the mining industry. For example, the units are used in chain tensioners, slewing ring drives and conveyor technology. However, their reliability, precision and high efficiency quickly made them popular in other areas of application.

Today, Düsterloh Fluidtechnik offers a wide range of hydraulic units for a variety of applications. The areas of application range from steel mills, production machines and shredders to the diverse application in the offshore, marine and shipyard sector.
